He first worked as a Radiographer and Sonographer, and later as a Graduate Assistant at the University of Calabar. Ernest obtained his PhD at the University of Sydney and is currently a Scholarly Teaching Fellow at the University. Ernest is a member of Sydney Catalyst Translational Research and Cancer Research Network. He currently serves as the coordinator of the Medical Image Optimisation and Perception Group (MIOPeG) Laboratory meetings at the Brain and Mind Centre of the University of Sydney. He is a keen researcher and reviewer for many peer-reviewed international journals. His academic prowess has been recognised by the prestigious Radiography Editor's Choice Paper, and the best presentation award, Publons top reviewer medal, and Outstanding Teaching (Early Career) awards.

Research interests

Ernest's research interests include breast density, breast cancer biomarkers, optimisation of breast cancer detection, models for risk and treatment outcome prediction, medical image perception, dose optimisation, radiographic and ultrasound image interpretation, and novel radiological tools for breast density measurement and image display.

Teaching and supervision

Dr. Ekpo coordinates four core units of study across the Undergraduate and Masters programs in the Disciple of Medical Imaging Science. He is also involved in Honours, Masters and PhD research Supervision.
